SHOCK-assomme PAD.

Specification of lLetters Patent.

Application led November 4, 1908. Serial No. 481,001. v

Patented Nov. 2, 1909.

To all whom 'it may concn:

Be it known that I, LEON R. NoDiNE, a

citizenof the United States, residing at duce a shock absorbing pad orcushion adapted for generaluse wherever it is required to absorb shocklas upon typewriting and add-A erever a yielding cushion ing machines orW 1s required, as upon furniture, my novel pads or cushions beingespecially adapted for use on office machines Vin which blows'arestruckv vby keys as adding and typewriting mai chinos, cash registers,etc., as by" absorbing the shock `of the blowsthey greatly lessen thenoise made by thel machines vand lessen the cost of repairs and' prolongthe-life of the machines.

With these and other objects in view I have devised the novel pad. orcushion 'of which the following description in connection withtheaccompanying drawing is a specication, reference characters being usedto indicate the several parts.

. Fi ure 1` is a plan view of one form of my nove pad Fig..2 a sectionon the line 2-2 in Fig. '1, the threaded shank being in elevation; and'Fi illustrating variant forms of attaching means. My novel pad is moldedfrom any suitable elastic material as soft rubber, and the essentialfeature of theinverition is` that thev pad isv provided with top andside walls inclosing a space so that the top wall is supield centrallyunder the weight of the art1cle placed upon it.

It .will of course lie-'understood thatlthe special shape of the pad iswholly unimportant so `far asA the present invention is concerned.

I have illustrated pads made'ml the form of a truncated cone as I havefound them in practice to work admirably with a relatively wide base. j

The pad consists simply of a wall of elastic -material made ofsubstantial thickness which incloses an air space in the center and mayor may not be provided with attaching means. 10 denotes the wall ofelastic material and 11 the closed recess. The process of making',

'. 3 and 4 are sectional viewsrr witl'a head 13 which may be molded insaid top or upper wall ofthe pad or -niay lie wholly within therecess asshown in the drawing, the material olf the wall closing tightly abouttheshank'" Inusing' this form, holes are tapped 1e nnder" side of thcframe of the machine and four, more o r less,

of the pads areattached to the machine by turning the threaded shanksinto the holes. In the form illustrated in Fig. 3. I have shown the padas provided withv a smooth shank, indicated by 14, which may be made ofmetal or wood, as preferred, and. which is centrally connected withthetop wall 10a. In this form, the shank is shown as provided with a groove15 into which the top or upper wal-l of the pad fitscloscly and with ahead 16 lying within the recess. yThis forni of shank may be molded intothe pad as already described or in either ofthe forms the pad may bemolded with a hole in the top or upper wall thereof and the head may beforked through the hole. It sh0'uldl benn derstood that the specialmeans of attachingr the shank to the. pad is not of the essence of theinvention.

In F ig. 4, I have illustrated a form-of pad adapted for use upon thelegs Lof chairs and 0the`1" articles` of furniture. The top or'ipperwall 10 ofthe pad in this form is provided with an upwardly extendingcircular fiange 17 forming a socket 18 )vhich closely receivesthe vvlegof-a chair or other article of furniture.

In each form, the structure is such that the article to which the pad isapplied is retained centrally and its weightis yieldingly supported b ythe top wall 10a. the latter hcing supported mainly or wholly at itsmargin, by the wall 10 which is ot' substantial thickness. The structurepermits of a maxiicoA mum of elastic support for the article while atthe same time avoiding` any liability of objectionable lateral movement.

Having thus described my invention, I claim:

1. A pad of the character described, comprising a top wall and acontinuous circular support-ing wall for the margin of said top wall,the whole being integral and of elastic material and having a fiatbottom, and means whereby an article resting upon the top wall may beretained centrally thereon.

A pad of thecharacter described, com- Qaasgn lprisinga top wall, andaan-continuous circular downwardly aring sup orting wall for the 15means whereby an'article resting'upon the A top wall may be retainedcentrally thereon.- 20,'

In testimony whereof I aiix my signature, in presence of two witnesses.
